Introduction- what is an SSD

Solid state drive or SSD works along with the processor and memory for accessing and storing data. As an external storage device, it can store data on a permanent basis for future use. It is one of the necessary components that can handle large amounts of data. Like hard disk drive, it stores data which is used by the CPU. But, there is a major difference between a hard disk drive and solid state drive that changes the functionality, accessibility, and overall productivity.

Solid state drive can store data on a permanent basis. In this role, it is similar to an HDD as it can handle lot of data and store it as a long-term option. This capability allows it to store large workload. Unlike a memory or RAM that can keep the data only long as the system is on, SSD and HDD can store data even after the system is off. 

SSD and HDD use different technology for storing and using the data. An HDD has mechanical moving parts for this purpose. It consists of a spinning platter and an arm. The arm moves over the platter for reading each portion of data. This mechanical movement can provide the data that is finally used by the CPU for the processing. On the other hand, SSD does not consist of any mechanical moving parts. Instead, it uses flash memory for storing and accessing data.

Due to the lack of a mechanical arrangement, it is able to deliver instant results. The absence of the spinning platter and arm reduces the additional work involved in mechanical searching. It can deliver instant results with significantly lower load times. The flash memory technology is similar to the ones used in smartphone, tablets, and other smart devices designed with an aim for faster processing and quick returns.

How does an SSD work?

As an external form of storage, an SSD can store large volumes of data. It is a convenient tool when you may need to work with a huge workload. Besides, as it saves the data on permanent basis, you can access it anytime and anywhere. The external nature of the storage implies that can you use it a desktop computer or laptop.

While HDD stores data on a spinning platter, SSD uses flash memory chips. It is similar to a USB drive that uses flash memory. It has extremely low wait times. The flash memory technology is all about faster processing and lower wait times. It improves the overall performance and productivity of your system. Irrespective of the data size, an SSD can access the data much faster, making it an ideal choice both for personal and commercial usage. 

Be it operating systems, images, videos, games, media, music or any other data form, an SSD can store the data with absolute ease. In order to understand the functioning of an SSD, we can take a look at the interaction between an SSD, memory or RAM, and the CPU. If you would like to access a spreadsheet for some editing, you would select the particular file from your computer. The file is stored on your storage device. No matter what type of data is in a particular program or file, it is always saved on the storage device.

Faster processing with an SSD

When you click on the spreadsheet to open it, the processor transfers the data from the storage to RAM. Here, the CPU can access the data from the RAM and use it for the final processing. If the data is stored in SSD, the wait time is reduced to a great extent. SSD has an instant data transfer speed. This quick transferring makes it possible to transfer data at a much faster rate as compared to other forms of storage. It is much faster than the conventional HDD. With the instant transfer speed, you can expect much lower wait times. The spreadsheet can open as soon you click the icon, making it convenient for productivity. 

Finally, the processor can use the data from memory and give you the final output. SSDs do not contain any moving parts like the HDD. This reduces the chances of wear and tear. The SSD can last for a longer time as compared to HDD. As SSD cuts the time that is required for transferring the data from the permanent storage to memory, it plays an important role in speeding up the entire process.

You may not realize the significance of faster processing for something as routine as opening a word document as it consumes less data. But when the same task involves larger volumes for activities like gaming or videos, it creates a huge impact.

As media, gaming and other CPU intensive activities use huge loads of data, it helps to cut down the speed of data transfer. You would see significant faster speeds and less backlog. Also, the system would not slow down or force you to wait for a longer time while accessing the huge files. Due to this fast processing, you can opt for a new SSD for your system. If you would like to sell your used SSD or HDD, you can reach out to us at BuySellRam. We accept all types of new and used SSDs and HDDs for an impressive cash value. You can use the benefits for upgrading to a new SSD. 

Where is an SSD used? 

SSDs are used as external storage system in computer desktops and laptops. As they store data for running a majority of commercial applications, they are useful in desktops. Previously most of the systems employed HDDs. But as SSDs offer clear advantages in the processing speed, they are preferred over HDD. Most of the old computers may contain HDD, but the latest models may show more of SSD. Cost is one of the disadvantages that can limit the involvement of an SSD. Initially, as SSDs were quite expensive, they were not used in the desktops and laptops. The involvement of the latest flash memory increases the cost of SSD. As it does not contain any moving parts, it has a longer shelf life with near perfect processing capability. 

When cost acted a major hindrance for computer manufacturers, they used a smaller SSD as a system drive and clubbed it along with an HDD. The cheaper and larger HDD can store the large amounts of data as compared to the smaller HDD. But in recent years, there has been a significant price drop in SSDs. This has made it possible to use a larger SDD in most of the desktops and laptops. Besides, if a system does not contain an SSD, you can opt to buy it by yourself as the cost of SSDs have reduced to a great extent. By opting for an affordable SSD, you can expand your productivity. One option is to buy a single large SSD that can handle your large workload. If the system is a multi-drive computer, you can change all the storage devices to an SSD form. 

As SSDs contain flash memory chips for storing data, they are manufactured in a different manner. They come in a variety of forms, sizes, and types. The manufacturing process is quite complicated and advanced in comparison with an HDD. The difference in manufacturing technology leads to higher cost that may be almost twice as compared to an HDD. 

Advantages of an SSD

When you work with large volumes of data, you can clearly see a difference between SSD and HDD. There are several advantages that make it a clear favorite choice among users. As the price of SSDs continues to decline, it is found in variety of systems including high-end gaming PCs to entry-level laptops too. You can expect to see SSDs in mid-range desktops and commercial workstations as one of the necessary components for increasing productivity. 

Lack of moving parts

SSDs involve flash memory chips. Unlike HDD that has a spinning platter and an arm that moves over the platter, SSDs do not contain even a single moving part. Generally, when HDDs and traditional storage components have moving parts, they may tend to fail on a regular basis. Any mechanical process is subject to wear and tear due to mechanical failure. Besides, if a mechanical error arises in any of the moving parts, it can halt the entire data transfer process. 

As SSD lack a moving part, it can last quite longer and at the same time show a reliable behavior. It is portable and durable as compared to the HDDs.


Fast speed confers another major advantage to SSDs. It can transfer data to the RAM as quickly as possible, reducing the processing time required by processor. The processing speed can be measured in microseconds rather than milliseconds. Such a fast transfer speed can ensure a quick responsive behavior while running a variety of intensive applications.

Low failure

SSDs employ the latest flash memory technology that delivers impressive results. It does encounter any errors or failures when compared to HDD. There is low chance of malfunctions, making it a perfect choice for reliable and efficient storage. 

Small size and thin shape

As compared to traditional storage devices, SSDs are much lighter and thinner. They can store large amounts of data within a small structure. Most of the SSDs are ultra-thin and few millimeters in width. They are only few inches in length that makes it possible to fit them in most of the laptops, desktop, and tablets.

Size and design

SSDs come in different sizes, shapes, and types. Due to this versality of design, they can be inserted into a number of slots. They are compatible with graphics card slot, 2.5-inch drive bays, and M.2 slots. 

Longer lifespan

Typically, an SSD can last up to a decade. You can take advantage of a longer lifespan, while making the most of its faster processing speed and higher productivity. If you decide to replace a used SSD with a new one or upgrade multi-drive system with new SSDs, you can sell the used SSDs at BuySellRam.

Types of SSD

There are different types of SSDs that can affect the factors such as speed, capacity, and thermal output. You can categorize them into different shapes and sizes.


This type of SSD is the oldest version along the development line. It can work as a link between HDD and SSD. As it has a connectivity link between HDD and SSD, it is compatible with most of the motherboards for a variety of platforms. It delivers an average speed of around 550MBps. This is slowest with respect to the other SSDs. Another disadvantage includes the SATA cable that connects the storage drive to the motherboard. It may add an unnecessary clutter to the overall system.


    PCIe or Peripheral Component Interconnect Express slot are compatible slots that for inserting graphics cards. They can also insert USB ports and sound cards. Now the latest development in SSDs includes the PCIe SSDs that can transfer data at an exceptionally faster speed. The latest generation called as PCIe 4.0 drives can deliver read speeds of up to 5000MBps and write up to 4400MBps. They are quite expensive than the SATA counterparts, sometimes running up to twice the amount.


These are smallest types of SSDs delivering excellent speed and performance. They have extremely short pin connector that can save space on the motherboard. One probable disadvantage may include overheating. As M.2 SSDs are smaller, they may tend to heat to a higher temperature. Some of the M.2 SSDs may have heat spreaders to reduce the impact caused by overheating.


NVMe is non-volatile memory express SSD. You can combine the NVMe with PCIe express and M.2 SSDs to transfer data to and from the host. With this combination, you can take advantage of efficient speed for excellent storage systems. 

SSD or solid state drive can increase your processing speed by a significant margin. It is particularly useful when you have to handle larger volumes of data. The SSDs can work along with the processor and RAM to increase the data workload. With the latest flash memory chips and smaller and thinner design, it can be used in a variety of computers and laptops.
